To all whom it may concern.'

Be it known that I, JOHN JAMEs IRVIN, a citizen of the UnitedStates,residing at Bellwood, in the county of4 Blair and State`provision of means for elevating one of the sides as the car is dumpedin that direction and for supporting the side in position to be properlyengaged with its support, to* gether with means actuated by the side forautomatically rerighting the car after the load is dumped and forguiding the body into intimate contact with the body ofthe car.

Further objects of the invention will appear as the followingspecicdescription is read in connection with the accompanying drawings whichform a part of this application, and in which: v

Figure 1 is a side elevation. Fig. 2 is an end elevation showing thebody of the car in upright position. Fig. 3 is a similar view showing itin dumping position. Fig. 4 is a section on line 4 4 of Fig. 1 lookingin direction indicated by arrow.

Referring more particularly to the drawing 1 represents a truck of anysuitable type which is provided with a central pivoting sill 2 havingupstanding pivoting ears 3 which are-connected by means of the pivotalbolt 4 with similar ears 5 carried upon a central pivoting sill 6secured to the floor 7 of the car body.

The car body comprises the floor 7, the end members 8, and the movablesides 9 which latter members have their lower ends guided into closingposition with the ends and body by means of reinforcing brackets 10which are inturned at their ends so as to provide a cam surface 11adapted to engage the outwardly projecting fingers 12 carried by thefloor. The sides are also provided with connecting strips 13 havingprojecting lower ends 14 adapted to engage apertured i tion.

brackets 15 carried by the bottom. Bracing rods 16 are also providedwhich are bridged between the brackets 10 and a central rib 17 Pivotedatvone end in brackets 18 carriedy by the ends 8 are raising levers 19whosey opposite ends are pivotally connected in brackets 20 carried uponthe ends of the sides adjacent theirupper edges and carry suitablebracing arms 21 which limit the downward movement of the sides when inraised position as shown in Fig. 3. These levers have adjustablyconnected thereto adjacent their pivotal point with the bracket 18,suitable operating rods 22 which have their lower ends pivotallyconnected to the links 23 which have their inner ends pivotally mountedin ears 24 upon the central sill 2. In normal position, the lower endsof the rods 22 rest upon bracket arms 25 carried by the truck so thatwhen the car is tilted to one side, the rods 22 will rest upon thebrackets and force the levers 19 upwardly thus raising one of the sides.After the load has been dumped the side thus raised acts as acounter-weight to return the body of the car to normal horizontal posi-The fulcrum point ofthe levers 19 upon the rods 22 being arrangedadjacent the brackets 18, a considerable leverage is obtained by thecomparatively small weight of the sides 9. j lt will be noticed that thesides are freely pivoted to the leversfand are limited in their downwardmovement by the arms 21 so that when they are returned to operativeposition for closing the body, they will be properly guided intoengagement with the fingers 12 and the extensions 14 will properlyengage the apertured brackets 15. i j

Suitable chains are pivoted to opposite ends of the car adjacent eachside and similar chains are pivoted to opposite ends of the truck ateach side thereof, as shown at 26 and 27. Chains 27 carry the ordinarylever connectors ywhich are adapted to connect with the chains 26 so askto hold the car in upright'or load containing position.

When the chains 26 and 27 at one side ofk the car are released that sideof the car will be permitted to rise or tilt to the position shown inFig. 3. This tilting of the car brings the links 23 and the raising rods22 upon the brackets 25, thus producing a rigid support which when thecar tilts, will raise the arms 19 and thus elevate the side 9.

side of said car, brackets mounted at right angles upon said door, eachof said brackets l Having thus describedthe invention, what is claimedvisi f Y in a device of the kind described the combination of a dump car,saidcar having an open side, a door arranged to close the openbracketslto cause said vdoor to. contact With* said carga plurality ofsocket members carried by said car into `which the beveled ends` ofsaidtenons' arev arranged to project as said bracket cam surfaces areguided Within SaidY guides, yand means whereby said door is moved rintoengagement With said guides.
